How much does it costs to keep everything running?

We thought it fair for the people who support our work with their donations
every year to know how much the autistici.org/inventati.org infrastructure
costs.
Costs can be split up in two main chapters: connectivity costs for each
node of the a/i infrastructure and maintaining costs (covering hardware
costs, server replacements, and only exceptionally travel costs for those who
wind up fixing the impeding disaster :)

This means that every year we spend more or less 12.000 euros for the
survival of the infrastructure.
All the work the collective does for maintaining the infrastructure is voluntary
work. We survive thanks to the donations of people using our services.
